Aims: We aim to demonstrate that the Herschel ATLAS (H-ATLAS) is suitable fora blind and unbiased survey for debris disks by identifying candidate debrisdisks associated with main sequence stars in the initial science demonstrationfield of the survey. We show that H-ATLAS reveals a population offar-infrared/sub-mm sources that are associated with stars or star-like objectson the SDSS main-sequence locus. We validate our approach by comparing theproperties of the most likely candidate disks to those of the known population.Methods: We use a photometric selection technique to identify main sequencestars in the SDSS DR7 catalogue and a Bayesian Likelihood Ratio method toidentify H-ATLAS catalogue sources associated with these main sequence stars.Following this photometric selection we apply distance cuts to identify themost likely candidate debris disks and rule out the presence of contaminatinggalaxies using UKIDSS LAS K-band images. Results: We identify 78 H-ATLASsources associated with SDSS point sources on the main-sequence locus, of whichtwo are the most likely debris disk candidates: H-ATLAS J090315.8 and H-ATLASJ090240.2. We show that they are plausible candidates by comparing theirproperties to the known population of debris disks. Our initial resultsindicate that bright debris disks are rare, with only 2 candidates identifiedin a search sample of 851 stars. We also show that H-ATLAS can derive usefulupper limits for debris disks associated with Hipparcos stars in the field andoutline the future prospects for our debris disk search programme.
